[(Me3AlCTp3‐Me)Mg(AlMe4)], respectively, with monoanionic tripodal ligands. Treatment of sterically less demanding RCTp3‐R′ with Mg(AlMe4)2 produced isostructural dicationic “metal‐in‐a‐box” complexes of the type [(RCTp3‐R′)2Mg][AlMe4]2 (R=Me, nBu; R′=H, Me). Utilization of the superbulkyligands MeCTp3‐Ph and MeCTp3‐tBu gave monocationic complexes [(MeCTp3‐Ph)MgMe][AlMe4] and [(MeCTp3‐tBu)MgMe][Al2Me7] as
